Abstract (en)
[origin: EP1940135A1] The invention relates to a telephone apparatus that allows, when additional installation of a handset unit ends in failure, an immediate retry of the additional installation with appropriate procedure and operations. At additional installation of a handset unit, a base unit (10) transmits an ID of the base unit (10) stored in a base ID storage portion (24a), a handset unit number inputted through a base key matrix (23), and an extension command for indicating an instruction of additional installation to a handset unit (30) wirelessly using a setting channel. When the handset unit number received fails to coincide with a handset unit number inputted through a handset unit key matrix (36), the handset unit (30) transmits a failure-indicating extension completion signal to the base unit (10), and its operation ends. Upon receiving the failure-indicating extension completion signal, the base unit (10) displays an operating guide on a base display device (15).
